| Outline of Final Research Achievements |
We have modified the optical system that enables neural activity imaging and simultaneous optogenetics so that we can perform more stable long-term observation and manipulation of neural activity than the previous method. Using this system, we first investigated the computational mechanism underlying visual information processing and the role of PV neurons under the anesthesia. These results were published (Agetsuma et al., 2017). We also developed a new system by which we can perform training and behavioral tests of mice under the objective lens, which enables imaging and optogenetics before, during, and after the learning/training. We performed actual experiments using this system. We will proceed the analysis of the data to understand the computational mechanism underlying cognition, learning and memory, and publish the results.
